Effect of reversible torsion on the structure and mechanical properties of iron under severe plastic deformations in a Bridgman camera

详细

The effect of the reversible direction of rotation of the movable anvil of the Bridgman camera (torsion under high quasi-hydrostatic pressure at room temperature) on the structure and mechanical properties of commercially pure iron (steel 08kp) is investigated. It is established that a change in the direction of rotation of the movable anvil under torsion substantially effects the structural characteristics of deformation fragments and dynamically recrystallized grains formed under severe plastic deformations. The effect of the method of deformation on the internal distortions of structure and on the mechanical properties is analyzed.
